<H2>DESCRIPTION</H2><PRE>
       The  <STRONG>printw</STRONG>,  <STRONG>wprintw</STRONG>, <STRONG>mvprintw</STRONG> and <STRONG>mvwprintw</STRONG> routines are
       analogous to  <STRONG>printf</STRONG>  [see  <STRONG><A HREF="printf.3.html">printf(3)</A></STRONG>].   In  effect,  the
       string that would be output by <STRONG>printf</STRONG> is output instead as
       though <STRONG>waddstr</STRONG> were used on the given window.

       The <STRONG>vwprintw</STRONG>  and  <STRONG>wv_printw</STRONG>  routines  are  analogous  to
       <STRONG>vprintf</STRONG>  [see  <STRONG><A HREF="printf.3.html">printf(3)</A></STRONG>]  and  perform  a <STRONG>wprintw</STRONG> using a
       variable argument list.  The third argument is a  <STRONG>va_list</STRONG>,
       a   pointer   to  a  list  of  arguments,  as  defined  in
       <STRONG>&lt;stdarg.h&gt;</STRONG>.


</PRE>
<H2>RETURN VALUE</H2><PRE>
       Routines that return an integer return  <STRONG>ERR</STRONG>  upon  failure
       and  <STRONG>OK</STRONG>  (SVr4 only specifies "an integer value other than
       <STRONG>ERR</STRONG>") upon successful completion.

       X/Open defines no error conditions.  In  this  implementa-
       tion,  an  error  may  be  returned  if it cannot allocate
       enough memory for the buffer used to format  the  results.
       It will return an error if the window pointer is null.


</PRE>
<H2>PORTABILITY</H2><PRE>
       The  XSI  Curses  standard,  Issue 4 describes these func-
       tions.  The function <STRONG>vwprintw</STRONG> is marked TO  BE  WITHDRAWN,
       and  is  to  be replaced by a function <STRONG>vw_printw</STRONG> using the
       <STRONG>&lt;stdarg.h&gt;</STRONG> interface.  The Single Unix Specification, Ver-
       sion  2  states  that  <STRONG>vw_printw</STRONG>  is preferred to <STRONG>vwprintw</STRONG>
       since the latter  requires  including  <STRONG>&lt;varargs.h&gt;</STRONG>,  which
       cannot  be  used in the same file as <STRONG>&lt;stdarg.h&gt;</STRONG>.  This im-
       plementation uses <STRONG>&lt;stdarg.h&gt;</STRONG> for both, because that header
       is included in <STRONG>&lt;curses.h</STRONG>&gt;.
